My invention relates to a sprinkling apparatus in which aplurality ofsprinklers are arranged in groups in connection with a hose, such as anordinary garden hose and the objects of my invention are: a

First,'to provide a group sprinkling apparatus of this class in whichseveral sprinkler units may be connected with a garden hose in spacedrelation tov each other and serve as a support for the hose as well asfor sprinkling purposes;

Second, to provide a sprinkling apparatus of this class in which a partof the sprinkler unit also serves as a support for supporting the hoseagainst movement;

Third, to provide an apparatus ofthis class in which the sprinkler andthe support are rigidly connected with the hose in predetermined spacedrelation from each other;

Fourth, to provide a group sprinkling apparatus of this class in whichthe water pressure in the hose tends to form a sealed joint between thehose and the sprinkler unit;

Fifth, to provide an apparatus of this class in which each sprinklerunit extends through the hose for rigid and positive connectiontherewith;

Sixth, to provide a group sprinkling apparatus of this class in whichoneof the water distributlng members also forms a clamping means forsecuring the sprinkler unit to the hose; and

Seventh, to provide a sprinklingapparatus of this class which is verysimple and economical of construction, easy to apply, applicable for usein connection with conventional garden hose and which will not readilydeteriorate or get out of order. I

with these and other objects in view as will appear hereinafter, myinvention consists of certain novel features of construction,combination and arrangement of parts and portions as will be hereinafterdescribed indetail and particularly set forth in the appended claims,reference being had to the accompanying drawing and to the characters ofreference thereon which form a part of this application in which: I

PATENT OFFICE Similar characters of reference refer to similar parts andportions throughout the several views of the drawing.

The hose member l, sealing washers 2 and 3, clamp members 4 and 5,combined support and I, water conductors 6, water distributing andclamping sleeve 1, and water distributing adjusting nozzle member 8constitute the principal parts of my group sprinkler apparatus.

The hose member I is of any conventional type 10 of garden or irrigationhose. A suitable length hose of this class is used and the sprinklerunits are placed in the hose a suitable distance apart about five or sixfeet apart being the preferred distance, and various lengths hose may bemade 15 to suit.

One unit of the sprinkler unit will now be described. The hose isprovided with relatively smallholes la and lb in opposed relation toeach other and the screw threaded end 6a is inserted zo first throughthe hole' la and then through the hole lb in the hose member 1 to'form atight joint with the hose member side wall. Before the member 6 isinserted into the holes la and lb, however, it is provided with a clampmember 5 which is screw threaded on 'the threads 6a of the member 6 tothe end of the thread as shown best in Fig. 2 of the drawing andpositioned on this threaded portion 6a and resting against the upperface of the clamp member. 5 is a washer 3 which also is provided with arelatively small hole so that it stretches over the screw threadedportion 6a of the member 6' thus providing additional sealing meansinterposed between the clamp member 6 and the hose l. On the other sideof the hose is provided another.

' washerv 2 which is similar to the washer 3 andpositioned over thethreaded end and adapted to slip thereon is another clamp member 4similar to the clamp member 5 except that it is not 49 a provided withthreads, but slides'over the outer side of the thread to. Screw threadedon the upwardly extended end of the threaded portion 8a of the member 8is a water distributing and clamping sleeve 1- which is a hollowcylindrical member provided with a screw threaded lower end In which'isadapted to abut against the upper side of the clamp member 4 and whenthe member I is tight thereon tends to clamp the hose between the clampmembers 4 and 5 50 and compress the washers 2 and .3 and also compressthe hose so that it is substantially oval shaped, as shown best in Fig.2 of the drawing, so that when water pressure is permitted in the. hose,it tends to seal the joints between the hose 5 and the member t bycompressing the washers fl and t. This sleeve member i is provided withan open portion ll; which permits the water to pass upwardly and out atthe upper end of the sleeve l.

The member 6 is provided witha pointed end 6b to facilitate positioningit in the ground for supporting the hose. It is also provided with a toeach other as shown and are adapted to permit the water to pass out intothe opening 1b in the sleeve member I.

The upper end of the member 6 is internally threaded at 6! in which isscrew threaded the water distributing and adjusting nozzle member 8which is provided with a bevelled head portion 8a and is adapted to beadjusted upwardly and downwardly to limit the outlet between the upperedge of the sleeve member 1 and the head portion 8a of the nozzle member8. It is provided with an upwardly extending slotted lug portion db forreceiving a screw driver for adjusting the nozzle to regulate the flowof water.

Though I have shown and described a particular construction, combinationand arrangement of parts and portions, I do not wish to be limited tothis particular construction, combination and arrangement, but desire toinclude in the scope of my invention the construction, combination andarrangement substantially as set forth in the appended claims.

, Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a group sprinkling apparatus of the class described, thecombination with a conventional garden hose, of a combined support andwater conductor piercing through the hose at its opposite sides andforming a vertical support for the hose, said support being hollow fromthe interior the interior of the hose, and a sprinkling nozzle at theupper end of said support communicating with the hollow portion thereof.

2. In a group sprinkling apparatus of the class described, thecombination with a conventional garden hose, of a combined support andwater conductor piercing through the hose at its opposite sides andforming a vertical support for the hose, said support being hollow fromthe interior of the hose upwardly and communicating with I of the hoseupwardly and communicating with with the interior of the hose, asprinkling nozzle at the-upper end of said support communicating withthe. hollow portion thereof, spaced clamp members on said support onopposite sides of said hose, and resilient washers interposed betweensaid clamp members and the side walls of said hose on opposite sides.

4. In a group sprinkling apparatus of the class described, thecombination with a conventional garden hose, of a plurality ,ofsprinkler units secured to said hose'in spaced relation to each other,each of said sprinlding units including a support adapted to be forcedinto the ground at its lower end and piercing through the opposite sidesof the hose and provided with a bore at its upper end communicating withthe interior of the hose, a sprinkling nozzle at the upper end of saidsupport, means for clamping said hose tightly on the support for sealingthe joint between said support and the hose, and a portion of saidnozzle forming a portion of the clamping means.
